In our private lives we defend ourselves from the marketing messages out to get us, our defenses made stronger for having spent the day at work trying to drive axes into our customers’ heads. We do both because the axe is already there, the metaphorical embodiment of that wedge Toffler wrote about — the one that divides our jobs from our lives. On the supply side is the producer; on the demand side is the consumer. In the caste system of industry, it is bad form for the two to exchange more than pleasantries.

But once the value of all the produced or built capital (what many of us think of as capital) are added up, the economists found something big was still missing: the vast majority of world’s wealth! If one simply adds up the current value of a country’s natural resources and produced, or built, capital, there’s no way that can account for that country’s level of income.

The rest is the result of “intangible” factors — such as the trust among people in a society, an efficient judicial system, clear property rights and effective government. All this intangible capital also boosts the productivity of labor and results in higher total wealth.
